If your morals are based on principle, then no matter who the person was, your decision would remain the same.
I believe/hope that I am the type of person who would not take anothers' life no matter what the circumstances because I want to be a person of principle. If there were some situation where I did take a life, then I am not the principled person I think I am.
Take the example of Google and their motto,'Don't be Evil'. It was a nice bit of marketing, but when the value of doing business with a repressive government was high enough, they and other company's apparently had no problems working with said governments to continue the repression of it's citizens.
Now, you may say, Google has left that country. But, it was not due to the moral repugnance they felt about repressing the citizens, but the fact they were under attack by agents/citizens of said government and felt it was no longer in their interest 'financially' to stay.
